Abstract
Conjugate mode of heat transfer experienced in solar cooker cavity is presented in this paper using computational fluid dynamics (CFD) approach. Trapezoidal-shaped box-type cooker has been used to investigate the heat loss from cooker cavity. Steady laminar natural convection and radiation inside the trapezoidal cavity having hot bottom, cold top isothermal wall and adiabatic sidewalls are considered. Forced convection due to wind flow on the top of the glass top cover and radiation is considered as well. The losses due to convection and radiation are considered from the top glass cover as well. Parameters like bottom plate temperature, emissivity of the plate and wind flow over the top cover are found to be more influencing on the heat losses from the cavity. Based on the results using CFD approach, the suitable parameters may be chosen for design of solar cooker cavity better and optimised performance.
